How does a wood pellet equipment job?<br>
Typically, wood pellet machine can be classified right into flat die pellet equipment and ring die pellet machine.



Ring die pellet mill has large volume and also high capability. It is suitable for factory usage and also large-scale production. Flat die pellet mill is small as well as portable. It has lower ability, ideal for home usage as well as small-scale manufacturing. The price of flat die pellet mill is much less than ring die pellet mill



Framework of flat die pellet mill.

From top to bottom, a flat die pellet mill is composed of a feed receptacle, an upper cabinet, a discharge outlet, a pin box, transmission, a transmission shaft, an electrical control cupboard, an electric motor, a engine base, and also 4 wheels, etc.



The electric motor can be replaced by a diesel engine, gasoline engine, or a PTO connector.



The core components: roller and also flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are installed in the upper cabinet. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is constructed from remarkable alloy steel, whose firmness is 55-60 HRC.



There are numerous openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are the most typical types. They understand the very best compression proportion with a multitude of experiments, ideal for more than 30 sort of materials.



The clearance in between the roller as well as flat die is 0.1-0.3 mm. This is where the raw product layer types. There are 2 changing nuts on the side of the pellet mill, you can adjust the clearance to adapt to various materials.



Just how does a flat die pellet machine job?

When you feed basic materials right into the pellet machine with the hopper, they fall on the flat die and spread over it under the feature of roller.



When you start the pellet machine, the electrical motor runs and bring along the major shaft via the transmission. Journalism roller is installed on the major shaft, so it revolves around the major shaft. Meanwhile, the rollers rotate around the roller shaft.




The rotating press types solid stress and also press the raw products right into the holes on the flat die. The raw products obtain molded in these openings. When they are ejected, they end up being strong cyndrical tubes. At the same time, the solid friction in between roller and also die warm up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They boost the adhesive pressure of products.



The size of the pellets is established by the hole size of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cyndrical tubes, the slicer under the flat die reduced them into particular size. You can readjust the placement of slicer to change the length.



After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal pressure, the pellets are sent out though the discharge outlet.



2 kinds of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned kind as well as die-turned type. The previous one has its flat die mounted on the major shaft. When the equipment works, the flat die turns as well as the roller maintain still. The later one has journalism roller set up on the main shaft. The roller rotates with the main shaft, while the flat die maintain still.



Roller-turned kind takes on much more efficient framework. It has bigger capability and also even more durable gearbox. But Die-turned kind is more small and also mobile, with reduced price. Certainly, both of them are able to make high-grade pellets.



Benefits as well as weak point of flat die pellet machine

Apartment die pellet mill has simple framework. It is little, light as well as portable. The expense is a lot lower than ring die pellet equipment It is simple to run and keep. You can observe the pelletizing process and solve any mistake in time. So it is preferred with farmers, house individuals, and also little fuel production plant.



The flat dies are using components, you need to replace it consistently. But it can be utilized with both sides. You can transform it over when one side has broken. By doing this you can expand their functioning life and also decrease cost.



On the other hand, the moving distance are various in the inner as well as outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, numerous flat die pellet machine embrace conical roller to fix this trouble. TICO flat die pellet machine takes on conical roller and also remarkable alloy steel in the flat die.

Besides, the get in touch with area of roller and flat die is smaller than ring die pellet machine, so the manufacturing ability and forming price is lower.



Exactly how does a ring die pellet equipment work?

Framework of ring die pellet machine

A ring die pellet equipment is composed of a screw feeder, conditioner, roller and also ring die, discharge port, electric motor, gearbox, pedestal.



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor get in touch with the gearbox through a shaft coupling. The gearbox bring along the primary shaft, and also the main shaft bring along the rollers. So the roller started to revolve inside the ring die.




When you feed resources right into the ring die pellet equipment through the hopper, they are sent to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw materials aims to enhance the sticky pressure and also creating rate.



Then, the refined basic materials will certainly be transferred to the pelletizing closet. Under the centrifugal pressure, they are dispersed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The high temperature and high pressure reason physical as well as chemical adjustments to the raw materials.



When they are ejected from the ring die, they become solid round sticks. The sticks expand much longer, until they are cut by the slicer outside the ring die. After that the pellets fall down and come out through the electrical outlet.



Two kinds of ring die pellet machine

According to different positionings of the ring die, there are vertical ring die pellet equipment and horizontal ring die pellet equipment.



In the horizontal kind, the ring die is put vertically. When raw materials fall down from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In diy wood pellet maker , the ring die is placed horizontally. The feed receptacle is right above the ring die, as well as the raw products falls under the ring die directly.



In the upright ring die pellet equipment, both the roller and also ring die turn. They develop centrifugal pressure as well as disperse raw materials consistently. In the straight ring die pellet machine, only the ring die rotates. pellet filling machine are distributed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet machine.

Ring die pellet mill includes high capability. The manufacturing per hr is from 800kg to 20t. As for flat die pellet machine, the ability is from 100kg/h to 1t/t. So if you production demand is under 800kg, you would certainly much better choose flat die pellet machine, or ring die pellet equipment is more suitable.



Because of the high manufacturing, the power consumption per unit is reduced. The abrasion in between roller as well as die is smaller. The operation and maintenance is easy. The pellets are consistent in size.
